Reinier,
I wrote out a long response to each of your points, but I realized
that perhaps what it boiled down to was something I said in my
previous message: "I'm not objecting to versioning in principle, but I
think there are enough unanswered questions that this proposal is
probably beyond the scope of "small changes"."
You are saying that if I have a problem with something, it is the
-source flag. You are absolutely right: I have problems with the
-source flag. Those problems should be sorted out before we include
it in the language. Each solution to each of these problems makes
this change larger:
1) API / Classfile compatibility
2) Backticks for identifiers
3) A need for thorough documentation for each potential version we
support. (You seem to be suggesting that this would be
implementation-dependent, but that's unlike everything else in the
language. Java is historically opposed to things that are
implementation-dependent. Part of the selling point of Java is that
code written for / compiled on a version of Java 7 will work with /
compile on all compliant Java 7 implementations.).
4) Is "source" really necessary at the top of the file (you seem to be
agreeing that it is), and if so, is that what we actually want?
I also think it would be worthwhile finding out how this proposal gels
with the module system they are introducing.
Fundamentally, it seems to me to be a large problem to solve, and I
think the right answer is to start a proper JSR and make sure you get
it right.
It is, of course, by no means important to Project Coin that I (as one
person) happen to think that this change is (or should be) too large.
But I suspect that I'm not the only one.
Jeremy
